To alt 'whom t may concern.'

l Be" it `known that i, Hamm JfUNotIoirAnN, a citizen @of the United States of America, and resident .of Davenport, Scott county, iowa, have invented a certain new and usefui improvement in Wick Raising and Lowering Devices, of which the foliowing 1s a specication.

My invention reiates 'to a device for automatica'liy raising or lewei'in a wick of an oil lamp or the epenir@ or c osrilngf-of :a lgas jet, and consists in the combination, 4with the lighting or extinguishin devices, of a clock mechanism by means o which the device becomes Voperative at any predetermined hour.

The principal object of my invention consim in themattachin of an ordinary .standardalarm clock to oil burner of an Aoil stove or heater, utilizing the usual alarm operating mechanism of the clock to manipulate the wick raising vice. This I accomplish in the manner hereinafter fully descrlbed and as particularly pointed out in the claims.

1n the drawings: Figure 1 is a fragmentary View of an oil heater showing in vation the base containing the burner and oil reservoir with my improved mechanism in place. Fig. 2 is a vertical cross section of the same portion of the heater. ig. 3 is a sectional view of a detail of my improved mechanism.

Similar numerals refer to similar parts in the two views.

The oil heater (the lower portion only of which is shown) together with the burner and clock are of the usual construction and form no part of my invention.

To the outer end of the usual wick raising spindle 1, is secured the bevel gear 2. Supported on the shelf 3 which is securely attached to the body of the heater, are the bracket bearings 1 -4 and an ordinary alarm clock 5. Spindle 6 is an extension of the usual alarm spring winding post and is supported by the bracket bearing i- 4a and fitted with the usual winding key 6a at its outer end. The alarm clock is so positioned relative to the heater as to locate spindle 6 at right angles to and in the plane of spindle 1. Slidably mounted on spindle 6 at about its center of length, is the bevel pinion 7. Through the medium of grooves 9 and 10 in spindle 6, ball 8, spring 11 and retaining screw 12, pinion 7 can be held Clamped to the .locked thereto t rough one of the counter-v and lowering deinto and out of engagement with gear 2. lit

is .secured to the spindle 6 and caused to rebate therewith by the pin 13 which is rigidly fixed in the spindle with its ends entending into the slots la in the extending heb or 'sieeve portion of .the pinion. Thus --it is seen that whether the pinion was in the position as shown in ig. i with the'iiali 8 resting in groove 10 or moved to a position with the ball engaging roove 9, tile pin S18 would always engage -te slet 14.

Theottter face of the bevel gear 2 is pne- With a series of counter-leeres or holes 15 drilled partly through the web of the gear near the inner edge of the gear teeth. 'phery of the gea-r 2 and bores 15 and the winged stud 16 is the llimiting stop 17. This :limiting stop conside of a finger hold handle bifurcated at one end. @ne leg of the lloifurcation being longer than the other and extending back of gear 2 engaging spindle 1. The other or ,shorter flog of the bifurcation extends over the edge and face of gear 2, carrying the winged .stud 16.

.A pilot light 18,' consisting of the small tribe 19 wick 20 and thelusual raising and lowering ratchet 21, is located adjacent the tube 22 of the large oil burner and so positioned as to bring the pilot flame in contact with the wick 23 of the large burner when same is raised above the edge of the tube 22 causing same to ignite. When the wick 23 is withdrawn into the tube 22, its dame will be extinguished Without affecting the pilot light which is always in readiness to re-light wick 23 whenever same is raised above the edge of its tube container.

After having wound up the alarm mechanism of the clock by turning the key 6 and the sliding pinion 7 is moved into engagementv with the gear 2 and automatically locked in such position by having caused ball 8 to be forced out of groove 10 and into groove 9, a release of the alarm mechanism at a predetermined hour, in the usual manner, will cause spindle 6 to revolve in a di'- rection opposite to that which it was turned on winding up of the alarm mechanism and rotate pinion Z of transmitting movement to gear 2, and will continue to rotate gear 2 until the limiting stop l? contacts the bracket L1- as shown in dotted lines 2li. This fixed extent of movement of gear 2 will have been found just sufiicient to raise wick 23 to become ignited by vcontact with the pilot bores 15.

combustion. `When it `llame and yet not too highto destroy proper is desired to extmguish the burner, pinion 7 is slipped out of engagement with gear 2 aad wick spindle 1 is rotated backward by throwing the limit-` ing sto 17 from the position shown in dotted mes to position shown in full line. When wick 23 burns shorter from continued use, its fixed limits of up and down travel are maintained by releasing stud 16 in limit-` ing stop 17, advancing gear 2 suiliciently and secure stop 17 in another of the counter- By extending spindle 6 suiliciently and .slidably mountm thereon another pinion similar to pinion only in a reversed position, it is seen that the wick could be lowered from a raised position at a predetermined hour just as it is raised from a lowered position as herein set forth. This fixed and predetermined. movement of spindle l by the mechanism described could also be directed to the opening or closing of a gas jet aswell as to the raising and lowering ofa wick. What'I claim as new is: 1.l In combination, an oil burner, a wick, means to raise and lower said wick at a predetermined moment consisting of a spindle operated by the clock mechanism of an ordinary alarm clock and provided with a slidably mounted bevel pinion, a bevel gear ca pable of engagement with said pimon and 1,ov4,ses

provided with an adjustable sto adapted t0 limit the extent of movement o said gear.

2. In combination, an oil burner, brackets secured 'to the base thereof, a spindle journaled in the free ends' of said brackets, adapte'd to be revolved by the clock mechanism of an ordinary alarm clock, a wick raising spindle extending from said oil burner and at right an les to and in the plane of the other spind e, a bevel gear on the wick raisin spindle, a bevel pinion`on the other spinle capable of engagement with said bevel gear,a spring actuated ball engaging grooves in the sindle adapted t0 ho d sald pinion into an out of engagement with said bevel gear.

3. In a mechanism of the class described, a rotatably mounted spindle provided with a bevel gear at one end, a spring actuated spindle located at ri ht angles to and intersecting the plane of t e first mentioned spine, .a pinion slidably mounted on one spindle capable of engagement with the bevel gear on the other spindle, and an adjustable limiting stop coperating\ with one of said gears.

Signed by me at Davenport, Iowa, this y 28th day of Aplril, 1913.
